I give up, WordPress-Drupal Import

Well, Ive spent 3 weeks trying to make the most of Drupal but WordPress has won out. I can turnaround my site using WP much faster and more effectivly that with Drupal as I have been having tonnes of problems.

I still have faith that Drupal is a better solution SO if I were to convert in a few weeks once I have got all the issues with Drupal worked out (maybe when 4.7 is ready?) how EASY would it be to import ALL my data from the WP database to the Drupal one??
